BRAKE AND BUFFER.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed February 1, 1907. Serial No. 355,336.

T all 11/71/0127, it may concern:

Be it known that I, FRITZ MoLLEn, a subject of the King of Denmark, anda resident of No. 14 T urnerstrasse, Hamburg, Germany, have inventedcertain new and useful which a piling up of the wagons, in case of anycollision, and also the resulting bouncings are avoided, so much so,that travelers would not feel the latter, and an extensive damage of thematerials, wreck, and loss of life will be reduced to a minimum.

The novelty consists, in the main, of the springs which are slidablyarranged in special hollow beams, fixed to the wagons, being connected.with the relative buffers, and the plate springs, which are verticallyarranged between the wagons respectively in connection with the slidablebars having brakes, so that in case of any unusual impact or pressuredoes occur between the wagons of a train, the latter springs wouldautomatically brake the wheels, and the former springs would take awaythe force or shock of the impact.

The novelty is devised in such a manner that their respective parts areindependently connected with the frame of the wagon whereby thedisadvantages which exist in the former styles of construction areavoided.

The accompanying drawing represents a form of construction of theinvention as applied to the wagons of railways.

Figure 1, shows the braking device which is operatively arranged withthe buflersprings respectively. Fig. 2, shows the butfer and thearrangement of the springs. Fig. 3, represents the buffer arrangementgoing through the wagon. Fig. 4, is a cross section view on the line ABof Fig. 2. Fig. 5, is a perspective view of the novel arrangementarranged in two ordinary wagons.

In both the longitudinal sides of a wagon,

hollow beams a are arranged having springs b removably attached toblocks p by the projections 1', which are in the respective blocks, andenter the respective springs. The

blocks p, situated near the ends of the wagon,

are provided with projections 6 adapted to work freely in the grooves dof the respective bars f which are slidably arranged in the beams abehind the springs b or toward the inner side of the wagon. Under thesaid bars and in the hollow beams on there are grooves 0 (Fig. 4) inwhich the arms 'L of the brakes Z can slide, and also the arm h,turnably connected at 7c, can swing inward upon the inward motion of thebars f, whereby the two brakes Z operate on the wheels respectively. Theprojecting ends of the said bars are provided with plate springs g,rigidly connected, in such a manner that the ends of the springs in onewagon get into the shoe-like indentations which are in the ends of thesprings of the opposite one, and the said springs are so situated, thatthey are actuated to move the bars only upon an unusual impact of thewagons of a train driving the buffers 0 beyond their limits, at whichthe barsf are pushed inward forcing the brakes Z against the wheels,which pressure is relaxed at the moment the butter springs I) arrive totheir usual positions, which action of the springs brings the said barsforward owing to the projections e in the blocks p catching at the endsof the grooves in the said bars; whereby the shock or concussion of thecol lision will be imperceptible in the wagons and the wagons will notbe carried away on the line by force of the collision as the brakes are.

automatically applied on the wheels.

In order to prevent the butter arrangement being driven out at theextreme end of a train, the blocks 10, situated at the two ends of eachwagon, are provided with screw bolts m which, on being tightened, holdthe blocks against the sides of the beams from slipping; the abovementioned brakes may be arranged to work with the ordinary vacuumbrakes.

The coupling of the wagons may be of the usual type. Owing to thespecial manner of construction, which conforms with the building of thewagons, the invention is adapted to be easily arranged or put in theirplaces.

I claim;

In the improvements in and relating to buffers and brakes for the wagonsof railways, the combination of hollow beams a with the wagons; springsb slidably arranged in the hollow of the said beams by connecting themwith blocks p which having the projections r inserted in the interior ofthe springs whereby the latter is kept in position; the blocks pconnected to the springs 1) near the ends of the wagon having aprojection e adapted to slide in the groove of the barf; the barsslidably arranged in the hollow of the said beams having arms i withbrakes Z, and the arms it having brakes l turnably attached so that thebars are adapted to apply the said brakes on the respective wheels whenthe bars are pushed inward by the force of a collision; the platesprings g rigidly fixed at the ends of the said bars, and the springsbeing provided with shoe-like indentations and corresponding plainsurfaces at their ends so that the springs situated in one Wagon Withthe plain surface at their ends, enter into the indentation of thesprings situated in the opposite one; and the screw bolts m provided atthe ends of the Wagon which are adapted to prevent the springs beingdriven out at the we I 5 shock of the collision, substantially as shown20 and described.
